---lhe lever, by imeans of which the operator abtuates the ratchet mechanism for rotating the-'' =-driv-ing feed-roller, :maybe operated either by ha'nd' or' byfoot. -In'the former case theilever would be'in the f0rm of afinger key which-"would most conveniently be placed alongside 0f and on substantiallythe same level as the ordinary keys of the typewriting machine; the fingerfkey' in question being; for example, on the front end 015 a lever=fulcrumed toward the back of the machine, and spring-pressure being :employed for returning said :keyllever'"todts normal or raised POSltlOIl. -Adju'stable stops may be provided for limiting themovement of the key lever'in each direction, and if desired, a devlce may be adopted for checking the rotation of thedriving feed=roller at the terinination of the operativestroke of the 'le ver." =5For this latter purpose the ikey lever,

on reaching the 'e'nd of its n'iovement, may

strike a lever adapted to bring a stop-pawl into' the path of tee'thmn -thef= periphery of a Wheel rota-ting concurrently: wi'th the driving feed-roller, as will 5 be f-readily under- .sto'od.

' In place of the manually-bperable arrangement: just mentioned, it is as a rule preferred to employ pedal-operated lever adapted to be depressed by the foot'of the operator and returned by spring-pressure, the operator being thus relieved oftheneces sity of r'emovirig his handiro'mthe ordinary keys ef-- the keyboard in order to actuate the =fer redto utilize bothfthemp and down movestroke for the purpose P o'f actiiatin g the ratchet me'chanisrn, employing for #this purposetwo driving pawlsg bo'th oou-pled'the lever: and resp'ectively caused; 'tooperatively engage the teeth 'of' the' ratc'het-wheel accordin'gmsthe pedal is being depre's'sed from or re-turnedto normal position A similar speed: of the driving feed wheel,- is in'dep'end' cut of the amount of tape that has been fed through the machine, so that a more uniform speed may be maintained than is possible where the web is wound on a driving spool whose effective diameter increases with the amount of tape wound thereon.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, which illustrate constructions embodying the invention, Figures 1 to 4 show one form of construction, Fig. 1 being a front elevation of portions of a typewriting machine to which the invention is applied, while Fig. 2 is a part rear elevation, and Fig. 3 a side elevation of the same. Fig. 4 is a side elevation, drawn to a smaller scale, showing the foot pedal and its connection with the ratchet-and-pawl mechanism. Fig. 5 is a rear view, similar to Fig. 2, showing a slightly modified construction.

The tape 11 containing matter to be transcribed is led horizontally across the front of the machine above the keyboard 12 in convenient position to be seen by the operator, being passed at one side of the machine through a stationary guide 13, and at the other side through a guide 14. Beyond the guide 14 the tape is gripped between the peripheries of a pair of feed-rollers 15, 16, whereof the roller 15 is held by springpressure in contact with the roller 16. The roller 16, which constitutes the driving feedroller, receives rotary motion through the medium of ratchet-and-pawl mechanism, from a lever 17 (Fig. 4) provided with a pedal 18 and mounted to oscillate about an axis 19 beneath the table 20 which supports the machine, the lever 17 being adapted to be depressed by the foot of the operator pressing upon the pedal 18 in opposition to a spring 21 whereby, after each depression the lever is returned to the normal or raised position indicated in Fig. 4.

The lever 17 operates upon the ratchet andpawl mechanism above referred to, through the medium of an upright connecting rod 22 whose lower end is pivotally attached at 23 to the lever While its upper end is given a substantially straight line movement by means of a pin 34 in the head of the rod, guided in a slot 35 in a guide bracket 36 substantially in a line intersecting the axle 24 of a ratchet wheel 25. The reciprocations of the rod 22 are converted into a rotary movement of the ratchet wheel 25 by means of driving pawls 26 and 27 pivoted respectively to the outer ends of arms 28 and 29 freely mounted at their inner ends on the axle 24 and extending on opposite sides of said axle, said arms being connected through links 31 and 32 to a pin 30 on the head of the rod 22. The pawls 26 and 27 are both adapted to drive the ratchet wheel in the same direction so that as long as the rod 22 continues to reciprocate, the ratchet wheel receives a practically continuous ro tation.

Fixed to the axle 24 so as to rotate with the ratchet wheel 25 is a gear wheel 41 running in mesh with a pinion 42 secured to the axle of the driving feed roller 16, the pinion 42 being preferably of smaller diameter than the gear wheel 41 to increase the length of web 11 fed at each reciprocation of the rod 22. Thus with the parts proportioned as shown in Fig. 2, the feed roller 16 will be given approximately a complete rotation for each movement of the rod 22 in either direction, although it will be understood that the ratio of the gearing may be varied as desired.

In the modification illustrated in Fig. 5, which is designed to meet conditions Where a less rapid movement of the tape 11 is re quired, the gear wheels are omitted and the ratchet Wheel 25 is mounted directly on the axis of the driving feed roller 16. In the construction shown in this figure, a. pin 37 on the head of the rod 22 forms a pivotal connection with a rock arm 38 which oscillates about a stationary axis 39 on a bracket 40; the arm 38 oscillating in a plane parallel to the ratchet wheel, and the path of the pin 37 being approximately in a line intersecting the axis 24 of the ratchet wheel, whereby both pawls rotate the ratchet wheel through substantially the same angle and at a speed approximately equal to that of the actuating rod 22. It will be understood that the means, shown in 5, for guiding the upper end of the rod 22, might be employed with the form of gear ng illustrated in Fig. 2, or vice versa.

In a typewriting machine of the wellknown Underwood type, the stationary guide 13, and the feed-roller mechanism together with the other guide 14, would be mounted on the frame of the machine at opposite ends respectively of the upper front horizontal member 43 of the frame which supports the usual scale 44. this member 43 (or the scale 44 carried by it) serving conveniently as a table or intermediate support to prevent the tape 11 from sagging. Obviously, in the case of languages or codes which are read from left to right, the stationary guide 13 would be mounted at the right-hand side of the machine and the feed-roller mechanism at the left-hand side as in the drawings. The supports for both these parts of the apparatus of the present invention may be integral with the frame 45 of the machine, or may be so formed as to be adapted for attachment to an existing machine. In the latter case the bearings for the rotary parts at the left-hand side, namely, the driving feed-roller 16, the ratchet wheel 25, and the gear wheels 41, 42, where such are cmployed, as well as the guide 14, the support for the spring-pressed feed roller 15, and the bracket 36 or 40, may conveniently be all formed upon a single bracket constituted by a casting or stamping 46 (Figs. 1 to or 47 (Fig. 5) adapted to be fixed, along with the several parts carried by it, to the frame of the machine, thus saving considerable trouble in fitting. If necessary, the intermediate support for the tape between the two guides 13 and 14 may be provided as an adjunct in cases where no existing member of the frame can be conveniently utilized for the purpose.

The feed roller 15 is of small diameter relatively to the driving feed roller 16, and its axis 48 is carried by a pair of arms 49 each fixed to a section of a rock shaft 50. A spring 57 presses the roller 15 against the web ll and the latter against the roller 16: the arms 49 serving as supplementary guides for the tape 11 which passes between them. The stationary guide 14 is shown as formed by a slot in the bracket 46 or 47, and is parallel to the axes of the rollers 15 and 16. whereas the guide 13 (see Fig. 1) is canted toward the front of the machine to cause the tape to be presented convenientlv for inspection by the typist.

In order to permit ready adjustment of the length of the connecting rod 22, it may be made in sections whereof one (preferably the lower one as in Fig. i) is tubular, the lower part of the upper section being slidable within the lower section and secured in adjusted position, a set-screw 52 passing through a collar on the lower section.

The periphery of the driving feed roller 16 is preferably provided with a covering 54' of rubber or other material adapted to exercise a secure frictional grip upon the tape. and the periphery of the other feed roller 15 may have a similar coating Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:
